*Deviation is referenced to the specified output frequency. For example, in the ECL model
CO-645VS at 155.52 MHz, at 25°C and -0.5V control, the frequency is at least 50ppm
below 155.52 MHz and at -4.5V control, the frequency is at least 50ppm above 155.52
MHz (negative transfer function for ECL units).
